Abstract: A receptacle for articles is provided for attachment by screws, clamps, rivets, or the like, to the underside of any chair having space available beneath its seat. In one preferred form, the receptacle is comprised of a fabric sheet having an elastic border along at least one of its edges. The fabric sheet, shaped to match the configuration of the seat underside, is inconspicuously mounted thereto such that said sheet is substantially flush with the seat underside. In use, access to the receptacle is gained by pulling down the elastic border, which preferably is provided by stitching a hem along one or more edges of the fabric and disposing an elastic cord therein. When the seat underside includes projecting nails, staples or the like, which may injure one reaching into the receptacle, an underseat cover is employed as a protective shield between the receptacle and the seat.
